In short, no.  The getaddrinfo(3) function doesn't provide a
timeout parameter.  However, I note that your operating system
may provide a mechanism to control the timeout used.  That is,
you likely can adjust your host configuration to avoid this
problem.

This issue will be closed as the requested change is not
possible.
